(2) Tsarin samarwa
The production process of machine-made sand can be generally divided into the following stages: block stone → coarse crushing → secondary crushing → fine crushing → screening → dust removal → machine-made sand. That is to say, the sand making process is to crush the massive rock several times to produce machine-made sand with a particle size of less than 4.75mm.
(3) Zabin tsarin yin zandari
Dangane da hanyar rarraba foda dutse, tsarin yin zandarin za a iya raba shi zuwa "yin zandarin mai laushi", "yin zandarin mai bushe" da "yin zandarin rabi bushe"; bisa ga tsarin aiki, za a iya raba shi zuwa "yin zandarin daban" da "yin zandarin taron"; bisa ga tsarin, za a iya raba shi zuwa "tsarin yin zandarin na tsaye" da "tsarin yin zandarin kamar hasumiya".
